SAN JOSE, Calif. (AP)  Ryan Bader made a quick and impressive debut in the heavyweight division, stopping Muhammed Lawall 15 seconds into the first round of the main event at Bellator 199.

Bader (25-5, 11 knockouts) sent Lawall sprawling to the mat with a crisp left hook  the first punch of the fight. Bader quickly pounced and landed repeated right hands before referee Mike Beltron stepped in to stop the fight, the last of the quarterfinal matches of the Bellator Heavyweight Grand Prix.

“I found the sweet spot,” Bader told the crowd afterward.

The 34-year-old Bader, who holds the light heavyweight crown, is attempting to become the first fighter in Bellator to hold two belts simultaneously in Bellator. Conor McGregor holds two championships in UFC.

To do it, Bader will have to win two more fights.

Matt Mitrione awaits in one semifinal match while heavyweight legend Fedor Emelianenko takes on Chael Sonnen in the other, with the winners advancing to the finals later this year

Some questioned how well Bader would do in his first heavyweight bout. One punch was all it took to answer.

Lawal (21-7) never recovered. Fighting for the first time since undergoing hip surgery in May 2017, ‘King Mo’ got crowned early and didn’t get back to his feet until the bout was over.

The two men had a history together, having gone against one another when both were in college.

The fight attracted some of the biggest names in the sport, including former UFC heavyweight champion Cain Velasquez, Daniel Cormier and Nate Diaz. Rapper 50 Cent and San Francisco 49ers quarterback Jimmy Garoppolo were also among those in attendance.

On the undercard, 42-year-old Cheick Kongo knocked out Javy Ayala with a short right hand to the chin midway through the first round to win in the heavyweight division. Jon Fitch outlasted Paul Daley to win a welterweight bout in the semi-main event by unanimous decision.
